We're dividing 76640289 by 723 
The aim is to understand the frequency of 723 in 76640289.

On to step 1:
The number 723 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 723

On to step 2:
When dividing 76 by 723, we get 0 with a remainder of 76.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 76 leaves us with 76.
Include the next digit (6) from the dividend after 76, then repeat: 766 / 723

Moving on to step 3:
The number 723 fits into 766 1 times, leaving a remainder of 43.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 723 from 766, we get 43.
Include the next digit (4) from the dividend after 43, then repeat: 434 / 723

Advancing to step 4:
When dividing 434 by 723, we get 0 with a remainder of 434.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtract 0 from 434 to get 434.
Bring next digit (0) of the dividend behind the 434 and repeat the process: 4340 / 723

Going ahead to step 5:
723 can be fit into 4340 6 times, resulting in a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 106.0
If we take 4338 away from 4340, we end up with 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 723

Going ahead to step 6:
22 divided by 723 is 0 with a remainder of 22.
Use 0 as the next digit of our solution. 
Result so far: 1060.0
The remainder is 22 after subtracting 0 from 22.
Include the next digit (8) from the dividend after 22, then repeat: 228 / 723

Let's proceed to step 7:
228 divided by 723 is 0 with a remainder of 228.
Put 0 as the next digit of the answer. 
Result so far: 10600.0
Subtract 0 from 228 to get 228.
Include the next digit (9) from the dividend after 228, then repeat: 2289 / 723

Advancing to step 8:
If we divide 2289 by 723, we get 3 and a remainder of 120.
The next digit of our result is 3. 
Result so far: 106003.0
If we subtract 2169 from 2289, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 9:
723 can be fit into 1200 1 times, resulting in a remainder of 477.
Use 1 as the next digit of our solution. 
Result so far: 106003.1
Subtract 723 from 1200 to get 477.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4770, and continue the process.

Going ahead to step 10:
The number 723 fits into 4770 6 times, leaving a remainder of 432.
Use 6 as the next digit of our solution. 
Result so far: 106003.16
If we subtract 4338 from 4770, we get 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

On to step 11:
723 can be fit into 4320 5 times, resulting in a remainder of 705.
The number 5 becomes the next digit in our result. 
Result so far: 106003.165
The remainder is 705 after subtracting 3615 from 4320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7050, and continue the process.

Step 12:
When dividing 7050 by 723, we get 9 with a remainder of 543.
The number 9 becomes the next digit in our result. 
Result so far: 106003.1659
Subtract 6507 from 7050 to get 543.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5430, and continue the process.

Going ahead to step 13:
723 can be fit into 5430 7 times, resulting in a remainder of 369.
Use 7 as the next digit of our solution. 
Result so far: 106003.16597
If we subtract 5061 from 5430, we get 369.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

On to step 14:
If we divide 3690 by 723, we get 5 and a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 106003.165975
Subtracting 3615 from 3690 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 15:
The number 723 fits into 750 1 times, leaving a remainder of 27.
The next digit of our result is 1. 
Result so far: 106003.1659751
Subtracting 723 from 750 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 16:
The number 723 fits into 270 0 times, leaving a remainder of 270.
The number 0 becomes the next digit in our result. 
Result so far: 106003.1659751
If we subtract 0 from 270, we get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

In conclusion, the division gives 106003.1659751 with a balance of 2.7e-07.
